MusicBee 用の Logitech プラグインを作成しています。私が持っている唯一の問題は、アートワークの画像、再生および一時停止の画像が読み込まれないことです。VS2012 リソース ファイル内のイメージを使用するさまざまな方法をテストしました。しかし、それらのどれも機能しません。イメージを dll ファイルにロードする必要があり、イメージは HICON または HBITMAP でなければなりません。以下は、私のプロジェクトの完全なクラスです。完全なプロジェクトはBitbucketにあります。

//This is the code I have used for loading an image.
    playIcon = LoadIcon (GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_ICON1));
playIconHandle = m_lcd.AddIcon(playIcon, 16, 16);
m_lcd.SetOrigin(playIconHandle, 2, 2);

  LoadImage(GetModuleHandle(NULL), ...)

これはプラグインでは正しくありません。GetModuleHandle(NULL) は、DLL ではなく、EXE へのハンドルを返します。リソースをプラグイン DLL に埋め込んだと仮定すると、DLL のモジュール ハンドルを使用する必要があります。これは、DllMain() 関数の第 1 引数で渡されます。
